Some backup applications execute backup tasks asynchronously. Consequently, the backed up virtual
disk or snapshot must remain alive until after the backup task is actually completed. This results in a
need for only one pre-backup script in most cases, that is invoked by the backup application before
it starts.
Alternatively, a CLI script can also do the whole task by activating the backup application from the
script itself (using the Run CLI command). A post-backup script (for clean up) may be invoked by the
backup application after task completion. If a post-backup script is not used, a PiT is maintained on
the original virtual disk until the next backup is performed.
In both cases, the pre-backup script must clean up before starting its actual work.
CLI command guidance
This section provides guidance that applies to all CLI commands. These examples are used for both
input from the command line or from an input file.
• Square brackets ([…]) mean optional. The pipe symbol (|) means alternative.
• The expression R|RW|OFF means that one of the alternatives (OFF, R, or RW) must appear in the
command where the expression appears.
• The expression 0|1|...|N means that one of the alternatives (0,1,..., or N) must appear in the
command where the expression appears.
